SSL certificate and private key match each other. If you only have SSL certificate and no private key, please apply for SSL certificate again. Generating a CSR file will also generate a KEY key file (private key generation can be directly "CSR file generation", and tools can be found in major search engines)! This is very important. Please download the generated CSR file and key file to your computer for safekeeping. CSR files and key files are randomly generated. If they are lost and cannot be retrieved, you can only reissue the application request.

Overview: When an applicant applies for an SSL certificate, a CSR file and a private key file are generated. The applicant submits the CSR file to the SSL certificate authority of CA, thus generating the SSL certificate public key file. If it really doesn't work, you can also apply for SSL certificate from Gworg, and these documents will be provided as a whole.

Briefly describe the process of applying for SSL certificate:

1.CSR requests file generation (files include: private key and CSR file).

Second, provide CSR files to SSL certification authorities.

Third, after fixed authentication, obtain SSL certificate.
